| 词源 | B.O. Lifebuoy Health Soap, better known as Lifebuoy, ran its first “Lifebuoy stops B———O———” advertisements (with a two-note foghorn warning accompanying the “B.O.”) on the radio in 1933. Since then B.O. has become synonymous with bad body odor, though it is of course an abbreviation of body odor, which isn’t necessarily bad. |
